d)Am thinking

Answer 1

Hint: The sentence in the question shows the relation to the past in the initial part. In part A, a person is talked about. His qualities are talked about but there has been a change in the opinion in part B when the word ‘Now’ is mentioned. So, the blank should be filled with something that hints at a change in opinion or something that was done before but is not agreed to in the present anymore.

Complete answer:

If option a is used in the blank: I don’t think so, too; but I’m not sure now; the whole sentence falls out of place because the sentence indicates the presence of past thought and then the transformation of that confirmed thought into something unsure due to the presence of the word ‘now’. So, option a is incorrect grammatically.
Option b shows a thought process in the past and then indicates the change in the thought which is similar to the idea provided in the sentence. The sentence means that a specific person thought earlier that he was the best person for the job but now he is unsure about it in the present. Option b exactly represents the same idea. The sentences represent uncertainty and so does this option. So, option b is the correct option.
Option c ‘Think’ is a simple present and the sentence demands the usage of the words indicating a past thought and so this option is incorrect.
Option d also represents a form of present tense – present continuous tense and doesn’t fit in the sentence as it is grammatically incorrect. So, this option is incorrect.

Note: The three incorrect options are in the present tense form while the correct option is in the past tense which is required.
